Install dependencies

npm install

Initial test (confirm everything is set up correctly)

npm test 2>&1

Testing dape

Load config and helper functions

Run it

Now open ./src/__tests__/add.test.ts, set a breakpoint on line 5, and run dape:

• First with jest-internal-console (this one works)
• Next with jest-integrated-terminal (this one fails)
